Ethological, psychological and legal aspects of animal sexual abuse.

This report presents an analysis of sexual abuse of five three-month old calves that died as a result of injury. A subsequent police investigation concluded that the animals had been sexually abused by an individual affected with zoophilia. The calves received injuries in the anogenital region resulting in fatal internal bleeding. The wounds appeared to have been caused by inserting and manipulating an unknown object into the vaginas of the animals. Post-mortem examination showed rupture of both the rectum and vagina in each calf with massive haemorrhage into the abdominal and thoracic cavities. From the psychiatric and animal welfare viewpoints animal sexual abuse is linked to clinical veterinary ethology. Ethical and legal aspects of animal welfare are evaluated with particular regard to the cases described.
